Abstract (en)
[origin: EP0574588A1] A biaxially oriented high-molecular polyethylene film which has a fibril structure, is excellent in gas-permeability, surface smoothness, tensile modulus and tensile strength, and has a coefficient of static friction and a coefficient of kinetic friction of each 1.0 or less. The film is produced by removing a hydrocarbon plasticizer from a sheet prepared from polyethylene containing the plasticizer by extraction, stretching the sheet into an oriented film having a specific surface area of 70 m<2>/g or above and a fibril structure, and heating the film under a constant-length condition to reduce the surface area by at least 20 m<2>/g. This film is useful as a laminate film, filter and a packaging material for moisture absorbent. <IMAGE>
